Friday I stopped at the local oil distributor in town and asked them if they had any oil in there warehouse that met the sj /sl ratings and also told them what I wanted to use it in. After about 5 minutes of searching through rows of drums and pallets of cases we stumbled on a pallet of delo 300 30 wt and a partial pallet of texaco ursa 15w40. They also had about 100 cases of the delo 100 and a few cases of the delo 300 left. 30wt, 40wt and 15w40.
After talking with the warehouse guy who told me ,no one has asked for this stuff in about 10 years, I picked up a 5 gal pail of the delo 300 30 wt and a pail of the ursa 15w40 for 40 bucks.
According to the dates on these pails, they were filled in the late 90's.
My question is, with they available supply he has in stock and the price its available to me at, is this oil a good choice for my 345? I know its not swepco, but dang passing up 5 oil changes for 40 bucks plus a wix filter would be crazy.
I know they have removed all the good stuff from oil now thanks to the guvment and the enviroo bullshit agency, and according to the ratings this should have the goodies in it .. If im not wrong. The cases of the delo 100 say , recomended for use in all detroit 2 and 4 cycle engine and all heavy duty gasoline engines.
 
I was wondering about you just the other day, and here you are with another post.....were we on the same wavelength?

The delo 100, as far as I know is still available, I believe chevron kept it in it's line because of all the 2 stroke detroit diesel engines still in service.... It May not be readily available in all areas, however. It is a low ash oil to meet the detroit spec which calls for a <1% sulfonated ash requirement.

I personally would be hesitant to purchase an oil which was made about 15 years ago, even if it has not been opened, mainly because of the possibility of additive "drop-out" that is when the additives May have fallen out of suspension and are just laying there in the bottom of the container. I'm not sure if shaking up the can, like in a paint shaker in a hardware store would work or not as some of the additives May have agglomerated.

If you are so inclined to use it, then it would be up to you. The only way to be sure would be to have it analyzed by a reputable lab who is familiar with the different oil grades and ratings... That would probably add around $20.00 to the cost of each container you purchased. You May have got what you paid for......

Sorry, but I cannot be more definitive than that.

Thank for the info dave!!! Im gonna go back and pick up a quart of the oldest delo I can find in the cases cut it open and see if we have a fallout issue or is this possible, will it gather in the bottom as say a sludgey like substance or is this something ill not be able to see ? The analysis wouldnt upset me in the least bit if I would be able to use this old stock oil thats cost effective.
 
I was sure you would reply, but don't know who you replied to, as I'm not "dave!"

I'm not sure if the process you intend on doing would be visible to the naked eye unless it was highly sludged together. If you are interested in performing an oil analysis of the product, here is the website of probably the largest labs specializing in such. If you decide to use them, make sure to give as much information as possible, especially the api grade, and the age if you can discern that.

oil analysis, coolant analysis, fuel analysis, metalworking fluid analysis, fuel testing, oil testing, coolant testing — polaris laboratories™

Sorry about the confusion on the name, too many in this old ass head. Anyway I took pics of the specs on the ursa and there are none listed on the delo except the api rating which is cc/cd. The pic on the ursa is kinda hard to make out but its readable.
I was gonna ask you about the analysis bottles that are done thru the truck dealers an the validity of such. Once again thanks for the info and puttin up with guys like me lol

It appears that the delo 300 in the picture is rated as a diesel
only oil as there are no specs for gasoline (which would be prefaced by the letter "s".

"c" is a diesel oil which stands for compression
"s" is a gasoline rating which stands for spark

the ursa has a pretty old gasoline rating, and honestly, even tho you got a "good deal" I would not use anything older than an oil rated "sj." the sj was the precursor of sl which was the last oil rating before sm (which has the lowered additives for use in 2007 and newer gasoline engines)

if you have access to someone who utilizes used oil analysis, it would probably be cheaper to go through them than to go direct with a big company like polaris (horizon) who requires you to purchase 10 sample kits at one time. But, as I mentioned before, whatever you do is strictly your choice as I personally would not go back that far using oil technology that old.

Good luck, and it is no problem, I only consider myself as trying to do a service.

Let me know how it turns out for you.
